Sorry if this is dumb - I don't go to 3D films but I'm taking my niece/nephew out tomorrow and it was their choice. It's to see Brave again which I did have to see before in 3D and when I did we were given these Real D 3D glasses for the showing.

So - assuming the cinema allows you to bring your own (which I think so as my brother says he'll remember to give the kids their glasses) - is it reasonable to assume I can use the ones I've got as well? I'd rather try for an answer here than the cinema as they'll just want to sell me something

Also, the Brave I saw before was Cineworld Edinburgh and it's likely Cineworld I'll be going to.

I reckon you'll be fine most cinemas use the Real D system and glasses as standard (certainly Vue and Cineworld do)Having said that I was surprised to be given a set of Dolby 3d glasses for the EIFF screening of Brave which are quite different, but as that was at a theatre rather than a cinema they may have brought in different equipment to the norm.

You'll defo be fine then. The premiere was at the Festival Theatre (terrible venue for films but hey-ho) and they did take the specs back. They seemed a lttle sturdier made than the Real D ones so I guess they were a bit more expensive

IMAX can be different, but besides that any regular 3D film will be passive 3D format meaning the glasses you get from any cinema will work, as will any glasses for a passive 3DTV (I.e. a 3DTV with the cheaper glasses, not the battery powered ones).

Ah - the lovely people at our showing weren't bothered about getting them back

Cheers SHP. So does all this mean they use the same glasses for a film that maybe has about 10 minutes of 3D as they do for one like Brave that's completely done in it?

Not really giving advice here (you've probably got your answer already ), but I thought I'd share anyway. The only problem I ever had was when the glasses somehow didn't match up with the image, so instead of getting that nice 3D effect I had a bizarre reverse 3D thing going on.

Simple solution, flip the glasses upside down. Not that comfortable, but easy to stop noticing after a while as well (and didn't fall off)

Not much use for someone who has to wear them over glasses though, surely?

I just about managed it without moving my head too much

Speaking of which, I bought a pair of those novelty podracer 3D glasses when I saw TPM earlier this year, and wearing them over my normal glasses caused them to completely block my nose. Now that was uncomfortable
